摘要
目的探讨继发肺结核空洞及肺内其他病变的影像学特点,评价HRCT在空洞性肺结核诊疗过程中的应用价值。方法回顾性分析于我院确诊的肺结核患者110例,所有患者抗结核治疗过程中均动态行胸片及HRCT检查。结果 110例患者CT检查显示了156个空洞。其中厚壁空洞占57.1%(89/110);胸片显示40例51个空洞,其中厚壁空洞占55.0%(22/40),CT以及胸片两种检查方法在空洞检出率以及对空洞壁的分辨率上的差异有统计学意义(P<0.05)。空洞外肺内其他病变主要包括小叶中心结节、增殖性病变、局限斑片影、支气管播散病变、干酪性肺炎、小叶斑片实变、小叶间隔增厚以及胸腔积液等,HRCT对厚薄壁结核空洞的空洞外周围病变的检出情况在小叶斑片实变、小叶间隔增厚以及胸腔积液方面差异无统计学意义(P>0.05),而在小叶中心结节、增殖性病变、局限斑片影方面差异有统计学意义(P<0.05)。结论 HRCT能有效的反应肺结核患者的疾病活动情况,为指导临床治疗及评估传染性提供有效的影像学依据。
【Objective】To analyze the HRCT signs of the secondary pulmonary tuberculous cavities and lung lesions outside of the cavities in adult patients, and to evaluate the application of HRCT in the treatment of cavitary tuberculosis. 【Methods】Totally 110 cases with tuberculous cavities diagnosed by X-ray and HRCT were analyzed retrospectively. All the patients were examined with HRCT and chest radiograph in the process of anti-TB treatment.【Results】In this study, 40 cavities in 51 cases and 156 cavities in 110 cases were detected by X-ray and HRCT CT respectively. There was a significant difference in the detection rate of the two methods as well as in the resolution of the hollow cavity walls（P〈0.05）. There was no significant difference in the detection of lobular patch consolidation, septal thickening and pleural effusion of HRCT（P〈0.05）, while there was a significant difference in detection of centrilobular nodules, proliferative lesions, and patchy limitations（P〈0.05）.【Conclusions】HRCT type of the pulmonary tuberculous cavities and the other lung 1esions are valuable for diagnosis of active pulmonary tuberculosis, and also useful in evaluating the prognosis.
